LM Completes Initial EMI Testing to Enhance JLTV Design
(Owego, NY., April 24, 2008) -- Lockheed Martin [NYSE: LMT] has completed initial electromagnetic interference (EMI) testing of the next-generation vehicle it is building for the U.S. Army's Joint Light Tactical Vehicle (JLTV) competition. The tests are helping team engineers reduce risk and ensure JLTV program success by advancing the team's vehicle design in the early stages of development.
"As a systems integrator, we routinely perform EMI testing early in the design process to find sources of electromagnetic radiation that could interfere with other on-board electronic systems or enable enemy forces to detect the vehicle on the modern battlefield," said Louis DeSantis, vice president and general manager of Ground Vehicle Systems at Lockheed Martin Systems Integration - Owego. "Correcting any issues now through structural redesign and relocation or shielding of key subsystems is far less costly and time consuming than making the same improvements later, and will help speed development of this vital transport system to the warfighter."
EMI testing was performed on the JLTV Team's Combat Tactical Vehicle Payload Category B infantry carrier inside an anechoic chamber at Lockheed Martin Systems Integration in Owego NY. Insulated from outside radio signal interference, the chamber enables test engineers to precisely measure the emission levels radiating from specific equipment. Systems tested included radio antennas, displays, engine and transmission controllers and electrical components. Additional tests conducted on an outdoor range characterized the interactions of the vehicle's antennas, which will determine the optimum design of the communications suite.
The tests were performed by Lockheed Martin's Owego-based EMI Laboratory team, which recently gained accreditation from the National Voluntary Laboratory Accreditation Program (NVLAP). Run by the U.S. Department of Commerce's National Institute of Standards and Technology, the NVALP verifies that testing and calibration laboratories meet national and international quality and procedural requirements.
